CENTRIFUGAL MOLDING-MACHINE SPECIFICATION forming part of Letters Patent No. 635,770, dated October 31, 1899.

Application filed February 6, 1899. Serial 'No. 704,676. (No model.)

To (tZZ whom it may concern.-

Be it known that I, JOHN GRANER, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Centrifugal Draining-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled to in the art to which it appertains to make and use the same.

The present invention relates to centrifugal machines such as used for drying matter; and the object is to provide improved means :5 for molding the solid constituents of matter under treatment during the drying process, so that the yield of the machine will be in a condition not requiring further process 'of shaping, such as customarily pursued.

WVith the above-stated object in view the invention consists in a novel form of lining for the sides of the basket of a centrifugal machine, the essential elements of the same being recited in the appended claims and a 2 5 preferred form of embodiment thereof being specifically described hereinafter and illustrated in the accompanying drawings, of which- Figure I represents a well-known type of centrifugal sugar-drying machine in central cross-section with my invention embodied therein. Fig. II represents the basket of the machine in horizontal section with my improved lining therein, and Fig. III representsthe fragment of the lining detached and in perspective.

It is not essential to a full and complete understanding of the present invention that a detailed description be given of the wellknown type of centrifugal machine here shown, the basket of which is designated by the reference-letter a, its side walls being foraminous and covered on the inside with wire-gauze or other suitable material, as indicated at a, for the purpose of permitting the passage of liquid while catching the solid constituent of matter in the basket when the same is thrown outwardly by centrifugal force.

In carrying out my invention I construct a mat of a length corresponding with the interior circumference of the basket and a width. corresponding with the depth of the basket, this mat being sufficiently pliable to permit of its easily assuming a cylindrical form and constituting alining for the basket. This mat is composed of numerous longitudinal and transverse partitions b and b, which form between them a multitude of cells 0, extending through the structure of the mat, the end walls being somewhat thinner than the others, as shown at b in Fig..II, so as not to form an unnecessarily-increased thickness of material where they meet in the cylindrical form which the mat assumes when constituting a lining for the basket. The cellular construction of the mat is for the purpose of molding the sugar or other material into the desired form as the centrifugal action proceeds, and it will be obvious that when the charge of material in the basket is thrown outwardly by centrifugal force the solid mat ter will lodge in the cells of the lining, while the liquid passes through the wire-gauze a, which forms the bottom of each cell. When the centrifugal action is completed, the mat will be removed with each of its cells containing a solid block of sugar molded into the shape of the cell, and these blocks can be ejected in any suitable manner and the mat replaced in the basket.

The shape of the cells may be varied, according to desire, as to the form of the product. They are here shown as cubical for the molding of sugar in cubes.

It will be seen that my invention provides a very simple and easily-manipulated appliance which is thoroughly effective in practice.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is as follows:

1. As a new article of manufacture, a pliable structure adapted to take cylindrical form and constitute a lining for the basket of a centrifugal drying-machine, said structure being composed of numerous cells separated by comparatively thin walls and opening through the structure, said cells constituting molds into which matter in the basket may be centrifugally projected.

2. As a new article of manufacture, a pliable mat adapted to take cylindrical form and constitute a lining for the basket of a centrifugal machine, said mat being composed of numerous comparatively thin transverse and longitudinal partitions forming a multitude of cells opening through the mat and 10 adapted to constitute molds, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN GRANER. Vitnesses:
